Abstract (en)

[origin: WO2021214565A1] An energy cell (1) for converting heat into hydraulic energy, provided with a pressure vessel (2), wherein the pressure vessel (2) comprises two chambers separated by an impermeable and elastic membrane (5), respectively a first chamber (6) filled with a phase change material (23), and a second chamber (7) filled with a hydraulic fluid (24), wherein the energy cell (1) is provided with a shell and tube heat exchanger (16) for alternately heating and cooling of the phase change material (23) to switch the phase change material (23) alternately from the solidified to the molten phase and vice versa, such that a volume of the first chamber (6) increases and decreases alternately, wherein a wall of the pressure vessel (2) is provided with a passage (26) configured to permit, at a volume increase and/or a volume decrease of the first chamber (6), a flow of hydraulic fluid (24) respectively from and/or into the second chamber (7), wherein the shell and tube heat exchanger (16) comprise a number of straight tubes (17), characterized in that the tubes(17) have an external diameter with a maximum of 3.0 millimeters.
